This invention relates ,to shuttle feeler thread parters and clamps whereby the outgoing filling endis parted near the inner end of the shuttle and that portion leading'to the cloth selvage is clamped and ;moved frontwardly for the action of the temple thread cutter. v I r 'Replenishing looms are now ordinarily provided Withsome meansfor parting v and clamping the outgoing filling end and carrying it frontwardly to position the part leading to the cloth selvage for the action of the temple thread cutter, and as pointed outin the patent to Harry. A. Davis, No. 1,591,289, dated July 6, 1926, the clamped end of the filling is liable to be drawn from the clamp on the frontward'movement of the shuttle feeler. In the patent mentioned, the fixed and the movable partingmember and the fixed clamping member were associated to part and clamp the outgoing filling end, and in order to insure that the end of the filling should be properly clamped and held, the

movable parting member was provided with a thread clamping portion extending downwardly beyond the cutting edge of'the movableparter and preferably acting to clamp the threadprior tothe parting operation.

This construction has been found in practice to be eifective and satisfactory'and when the movable combined parter and clamp was opened, the scored face, constituting the clamp of the parting member, served/0 lift the thread.

It is desirable at times to have ready access to the cutting edge of the partingme'mher for sharpening or other purposes,"and the present invention therefore, is a. further development of the shuttle feelerv thread parter and clamp shown, described and claimed in the Davis patent.

One of the objects of the present invention is to provide a thread parter and clamp of the general character of that described-in the Davis patent, wherein ready access may be had to the cutting edge of the parting member to sharpen or repair thesamefl An 7 important feature of the present invention,

therefore, consistsin a shuttle feelerthread parter and clamp wherein the clamping member is separate from the parting memher and so connected thereto that the two members may be relatively moved to per.-

mit ready access to the cutting edgejof the parting member. 7

The invention and novel features thereof will best be made clear from the following description and the accompanying drawings o f'one good form thereof. i q In-the' drawings: 1

Fig. 4; is a plan View of the assembled thread parter and clamp. 1

The shuttle feeler 1 may be of any usual construction andpreferably is provided with thereoessed jaws 2 and 3 for engagement with the shuttle, should it not be properly boxed, and also for positioning the outgoing filling end for the action. of the thread parter and clamp. p 1; As is usual in looms having a shuttle feeler toascertain'whether the shuttleis properly boxed the shuttle feeler. is normally in front position and on call for replenishment of filling is moved rearwardly, but themeans for thus controlling the shuttle feeler is not here shown and described because the details thereof form'no part of the present invention and are now well un- IUD the movable thread'parter and clamp was constituted by a parting member having rigidly associated therewith the clamping member which extended below the cutting edge of the parter. In accordance with the present invention, :however, the movable lateral direction to hold the elements of the thread parter and 'clamp in associated relation.

As indicated more clearly in Fig. 3, the fixed thread parting member 4 has an opening 8 through which the .bolt 6 extends and is held in fixed position by means of a pin 9 engaging the bifurcated end portion 10 of the fixed parting member. Similarly, the

' fixed clamping member 5 is provided with an opening 11 through which the bolt or pivotal support 6 passes, and the bifurcated end'12 of theclamping member also engages the bolt 9, the construction being such that the fixed parting member 1 and the fixed clamping member 5 are held in fixed position on the shuttle leeler.

Interposed between the fixed clamping member 5 and the fixed parting member 1, and mounted for pivotal movement upon the bolt or pivotal support 6 are the movable parting member 13 and the separate or independent movable clamping member 1 1, each of which has a frontwardly extending tail portion 15 and 16. l

The parting member 13 and the clamping 1 member .14: are pivotally connected at 17,

Fig. 2, and the ilrontwardly extending tail portions 15 and 16 of the two members are detachably locked together by a bolt or pin 18 in order to cause movement of the parting and clamping members 13 and 1 1 as a unit in parting and clamping the thread. In order that the parting member 13 and the separate clamping member 14 when thus connected formovement as a unit may have pivotal motion about the pin or pivotal support 6, each is provided with an opening 19 through which the pin 9, which holds the fixed parting member and the fixed clamping member in their fixed position, passes.

Vhen the movable parting member 13 and the movable clamping member 14 are associated and locked together forclan'iping and parting the thread, the clamping portion 20 of the clamping member preferably extends downwardly beyond the cutting edge '21 ot the parting member, with the result that upon pivotal movement of the interlocked parting and clamping members, the thread will be first clamped and then parted, so

the invention, the clamping face of the clamping member 14 is preferably scored or grooved, as at 22, and since. the clamping surface of the clamping member precedes the cutting edge of the parting member during their joint movement to part and clamp the thread, the latter will be first clamped between the movable clamping member 14: and the fixed clamping member ,5, and thereafter, the cutting edge 21 of the part ing member will come into action to part the thread. V

Extending laterally from the tail portion of the movable clamping member is a pin 23, which on rearward movement of the shuttle l'eeler is actuated by an opening device, now well understood in the art, to cause the movable thread parter and clamp to open, as indicated in Fig. 1. The parts being in the position shown in Fig. 1 and the shuttle l eeler being in rearward position, the movable thread parter and clamp are actuated, preferably by-frontward move-' mentor the lay, to cause the two to move as a unit, first to clamp, and then part the thread, and on irontward movement of the shuttler feeler to carry the clamped thread frontwardly in position for the operation otthe temple thread cutter. I

As indicated in Fig. 1, the clamping portion of the movable clamping member 1 1 extends below the cutting edge 21 of the part-f ing member 13, and to permit ready accessto the cutting edge of the parting member, the present invention contemplates that the movable parting member 13 and the movable clamping member 14 may be relatively moved upon release of the lock 18 which nor.- mally acts to unite the movable parting and i clamping members for their joint operation in parting and clamping the thread, as indicated in Fig. 2.

WVhen access is desired to the'cutting edge of the parting member 13. the bolt or pivotal support 6 is removed, together with the washer 7 and fixed clamping member 5, as indicated in Fig. 3, whereupon the movable part-- ing member 13 and its associated separate clamping member 14 may be removed and upon disengagement of the lock 18 from the front-wardly extending tail portion of the said members. they may be relatively moved, as indicated in Fig. 2. to permit access to the cutting edge of the movable parting member.

During normal weaving operation, the movable parting member 13 and separate clamping member Mare locked together by the lock or bolt 18 for movement as a unit in clamping and partingthe thread, and

. ing members 13 and 14 for relative movement substantiall in the position indicated in Fig. 2, where y the parting edge Qlot the parting member may be sharpened or otherwise repair-ed.
